abstract = "We saw in Chapter 9 that when we discretize a CT reconstruction problem we arrive at a system of linear equations. In most of that chapter we used the notation f for the vector with all the pixel values, but in Section 9.5 we changed the notation for this vector to x in order to be consistent with the massive linear algebra literature. So our system of equations takes the form A x = b, where A is the system matrix, b is the right-hand side, and the vector x is the solution which represents the pixel values of the reconstruction we want to compute.
